Abstract
The invention concerns a device for remote reading of states, comprising a communication network (1), a plurality of peripherals (31 to 33) each of which adopts an instantaneous state (STAT—1 to STAT—3), and a controller (2) periodically scanning said peripherals (31 to 33) to read therefrom the instantaneous state (STAT—1 to STAT—3). The invention is characterized in that the communication network (1) electromagnetically connects the peripherals (31 to 33) to the controller (2), and said peripherals (31 to 33) are supplied with electrical energy via said communication network (1). The invention is useful for managing calls in lifts by means of peripherals not provided with any galvanic connection and with any individual power source.

A system for remote status readings, comprising:
- a communication network;
- a central controller linked to the communication network;
- and
- a plurality of peripheral devices linked to the controller through the communication network, each peripheral device adopting at each instant an instantaneous status belonging to a plurality of possible statuses, the controller being operative to periodically scan the peripheral devices to read their instantaneous statuses, the communication network being operatively provided so as to link the peripheral devices to the controller by radio frequency means, the peripheral devices being supplied with electrical energy through the intermediary of the communication network.
